— A dynamic delay model, which includes the nonlinear loading effect, the effects of the input transition time and the multiple-input triggering, is proposed for the gate-level timing simulation. It is shown that the developed delay model gives near circuit-level accuracy with comparable speed to other common delay models.
Real-time electromagnetic transient simulation system involves high computational tasks and is very difficult to achieve small time step. In this paper, we proposes the field programmable gate array (FPGA) design and implementation for real-time electromagnetic transient simulation system with double-precision floating-point calculation. The parallel… (More)
Because of the large-scale integration of wind power, dynamic characteristics of power system emerge a lot of uncertain influence. Only considering the most serious and credible accidents, traditional on-line security assessment system which is based on deterministic analysis methods can not quantitatively estimate the actual operating conditions of power… (More)
This paper presents a mixed topology of Power Electronic Transformer based on Three-Level converter and H-Bridges. It does take into account two conditions, which includes the development of power electronic devices and manufacturing level of high-frequency transformer in the future. First the paper introduced the fundamentals of PET, and then studied on… (More)
A unified and consistent representation of logic gates at logic and circuit levels is described based on the subcircuit expansion approach. A dynamic-delay model is proposed for gate-level timing simulation, which includes the effects of nonlinear capacitive loading, input transition time, and multiple-input triggering on the delay. It is shown that the… (More)
